The process of generating a DEXTL program for data extraction can also
be performed manually, instead of relying in the automated generation
from examples assigned in the browser. This way needs a complete
understanding of the DEXTL language (see ITPilot DEXTL Guide) and it is only recommended
for advanced users.

The outline of the process is the following:

Once decided what information is going to be extracted, create a
structure for that data in the Structure pane.

Highlight some data to be extracted in the browser and check what
tags are present in that chunk, using the Token Viewer pane.

From the tags of the web fragment, use the Generation pane to type
the DEXTL program that extracts the desired data.

Test the specification in the Specification Test pane, and repeat
steps 3 and 4 until all the data is extracted correctly.
